Specification of Letters Patent.

Application filed December 5, 1908. Serial No. 466,153.

To all whom it may concern: 7

Be it known that I, CHARLES UNION? BREWSTER, a citizen of the United States, re-f siding at Oakland, in the county of Alamedafi and State of California, have invented'ai; new and useful Automatic Ruling-Machine,

of which the following is a specification.

My invention relates to improvements in; machines for ruling a series of lines (of suchf equal distance apart as may be desired, or of; graduated distances, that is to say: Each line; varies in distance from the preceding one in increasing or diminishing ratio as may be desired) on lithographic stones, metal plates or in kindred processes or uses; and the ob: jects of my improvement are :a machine} which runs by means of a motive power and performs its various functions automatically and without the necessity of personal attention. In the accompanying drawings I have made use of a motive power, namely, elec-fi tricity, for the purpose of full and intelli-; gent demonstratlon of its automatic action; I attain these objects by the mechanism illustrated in the accompanying drawings, in

which Figure 1, is a perspective View of the en-@ Fig. 2, is a top view of the machine. Fig. 3, is a vertical front view of the entire machine. Fig. 4, is a vertical end; Fig. 5, is a vertical tire machine.

view of the machine. end view of the reversing gear. Fig. 6, is a front sectional view of the bar or plate with the lifting and graduating mechanisms. Fig. 7, is a top sectional view of the bar or plate with the lifting and graduating mechanisms. Fig. 8, is a perspective detail view of the reversing mechanism. Fig. 9, is a sectional view of the actuating arm of the reversing mechanism.

Similar letters and numbers refer to similar parts throughout the several views.

The frame A on the legs B constitute the track upon which the" traveling ways 0 move. On the ways C travels transversely the carriage D, suspended from which is the hanger E to which is pivoted the arm F with its counter-balance. Fastened firmly tothe arm F is the apron G by means of which the ruling point H fastened at the other end of arm F is raised or lowered. The carriage D is moved on the ways C by means of the Patented Aug. 31, 1909.

feed-screw I held in position by a collar K working in a bearing L with screw adjustment conta ned 111 the block J which 1s fastened solidly to the ways 0. This constitutes, practically, the regular mechanism employed in ruling machines at the present day.

The bar or plate 1, moves back and forth on the bearings 2, 2, the length of motion being governed by the shoe 3 acting as a stop, said shoe 3 being moved by the feedscrew 3 'which is controlled by the bevel pinion 3 and second bevel pinion 3, the last mentioned pinion being connected solidly to the ratchet 4 having a handle attached thereto, said handle being used to alter the position of shoe 3 as desired. On the projecting hub of the ratchet 4, is the rocker.-

arm 5, and on the said arm is the pawl 6, made to work either way as desired, and held in contact by a spring 6*. tension of right-hand bearing 2 hangs loosely the bar 7 which is connected at its other end to one of the holes in the rockerarm 5 by means of a screw,- a change in the holes making a change in the extent of movement of the rocker arm 5 and thus through the pawl 6, ratchet 4 and bevel pinions 3 3, screw-threaded bar 3 to the shoe 3, altering the position of said shoe 3 and thus the extent of movement of the bar or plate 1. The arm 5 and bar 7 constitute the graduating attachment and are used for this purpose only. A lockingfinger t holds the wheel 4 solidly at any desired place for regularly spaced ruling.

At the back of the cross-piece of the ways C, are fastened two L shaped bars, 8 and 9, which extend under the diagonally laid front bar of the frame A. A steel spring bar 10 carrying the grooved wheel 10 at one end, is fastened to bar 8, as at 8 and lies across bar 9 in which is a screw 9 to apply tension to the wheel 10,the purpose of which is to overcome the tendency to drawback of the ways C, caused by the movement of the bar or On the exwhich meshes with the loose-running gear plate 1 and the various movable parts actuated by or attached to the said bar or plate 1-.

Running from a bearing in bar 9 to a bearing in the bar 11 suspended from the ways 0 at the back, is the bar 12, which is eccentrically hung, and said bar 12 being straight allows the apron G which rests against it, to slide along as the carriage D is shifted. A short arm 13 is fastened to the eccentric bar 12 and held up by a spring 13, and is connected by a rod 13 to one arm of the crank 14, the other arm of crank 14 carries the finger 15. The lifting plate 16 is chisel shaped at one end, and attached firmly to the bar or plate 1, but projecting beyond it sidewise, and bears and travels on the top ofthe cross-piece of the ways C; thesaidlifting plate 16 raising or lowering the" finger as it moves forward or back.

On top of bar or plate 1, is the rack 17 18, projecting from which is the arm with pawl 19 thatengages the ratchet 20 fastened solidly'to the feed screw I.

Projecting from the cross-piece of ways C at either end, are the fingers 21, and fas-' tened underneath ways C is the loose hung Two bars, 23 and 24, moving freely in box-bearings, 25, 25, have movable thumbs 26, 26, and 27, with set-screws for fastening them securely to the said bars.

The fingers 21, 21, move the bar 23 by means ."of contact with the thumbs 26, 26, and the finger 22 moves the bar 24 by means of contact with thumb 27. The right-hand end of lbar'24 acts as a thrust to push the handle of knife-switch 28, and thus break conjecting from its side,

nection with the motive power, the lefthand end of bar 23 has two fingers 23 probetween which freely plays the weighted rod 29 and as the bar 23 is thrust by the fingers 21 forward or back, it throws'overthe weighted rod 29 causing .a reversing of the motive gearing.

The shoe 30 works freely on the Ways C and is used to hold up finger 22 clear of thumb 27, and the shoe 31 also moves freely on the ways 0, but has attached to it a rod 31 traveling in a bearing 31 on the carriage D, and held where desired by a screw the said bearing 31".

The reversing gear consists of a standard 39, in a bearing in which runs the main shaft 32, and on the said shaft is a double frame 40 carrying a set of gears, one of which meshes with gear 33 fastened to said shaft 32. Above is a short shaft 34 carrying gear 34, and having on its outside end a sprocketwheel 34", both fastened solidly to said shaft, and over the said sprocket-wheel travels the chain 41. The eccentric crank 35 works in a bearing in the standard 39, and is connected firmly to the arm 36 by means of a square joint and set screw. The other end of, the said crank 35 has a finger 35 that works in a slotted bearin 35 in the double frame, for the purpose of throwing the said double frame first to one side and then to the other, causing first one of the gears and then the other to enmesh with gear 34 and thus reversing the motion of said gear 34.

Fastened to the sides of arm 36 at the top, is the band 37, equivalent to and used as fingers for the weighted rod 29, which is pivoted to the said arm 36 lower down, the space between the said band or fingers allowing free play, for the purpose of avoiding a dead center. At the bottom of arm 36 projecting on either side, is the piece 38 bent at both ends to form stops or fingers which strike the sides of the stand 39, first on one side and then on the other; the object of which is to prevent the gear from meshing too hard and causing vibration or jerking, the additional is applied by means of the shaft 32, and

tliroughgeai's, sprocket-wheel 34 and chain 41, to the bar or plate 1 causing it to move to the left, this motion by means of the rack '17 turns gear 18 and through pawl 19 and ratchet 20 the feed-screw I, drawing carriage D forward transversely, at the same time the lifting-plate 16 raises the finger 15 and through 14 and 13 twists horizontally the eccentrically hung bar 12, forcin down the apron G and raising the ruling point H. The movement to the left continues until the shoe 3 strikes the left-hand bearing 2, causing the traveling ways C and all attached theron and thereto, to move to the left, until the left-hand finger 21 strikes the left-hand thumb 26 moving bar 23 to the left which throws the weighted rod 29 over against the finger band 37, and through arm 36 and eccentric crank 35 moves the engaged gear in the double frame 40 out of contact with gear '34 and enmeshes the reverse which starts the bar or plate 1 to the right. As the bar or plate 1 moves to the right and pawl 19 is running free on ratchet 20, bar 16 lowers finger 15 down the chiseled point, this movement through crank 14 and rod to the short arm 13 causes the eccentric bar 12 to turn horizontally, allowing apron G to rise, this lowers the ruling point H. When the bar or plate 1 strikes the bearing 2 it causes the ways C and all attached thereon to move to the right, drawing the ruling point across the surface, until the right-hand finger 21 strikes the right-hand thumb 26 moving bar 23 to the right and forcing the weighted rod over against the finger band 37, and through the arm 36 and eccentric crank 35, moves the engaged gear in the double frame 40 out of contact with gear 34 and enmeshes the reverse gear and repeats.

The shoe 31 attached to the rod 31, is

1 forward it gradually forces the shoe 30 along,

until the loose-hung finger 22 is released and drops, on the next movement to the right the said finger 22 strikes the thumb 27 fastened to the bar 24, giving it a thrust and forcing.

out of contact the knife switch 28, thus breaking the motive power connection, and

the machine stops.

The rocker-arm 5' and the bar 7 are used for graduating only, and as the bar or plate 1 moves back and forth, they cause the bevel pinions 3 and 3 to turn by means'of the ratchet 4 and pawl 6, thus causing the shoe 3 to move, forward or back, as the double pawl 6 may be set, thus altering the extent of the distance of motion of the bar or plate 1, and by means of rack 17, gear 18, pawl 19 and ratchet 20, the feed-screw I, altering the space between the lines.

The double pawl 6 being set one way will cause an increase in the distance of motion of the bar or plate 1, and also an increase in the distance between the lines, and when set the other way will cause a decrease. The connection of bar 7 with the different holes in the rocker-arm 5, will cause a greater or less movement of said arm 5, and thus a corresponding variation in the space between the ruled lines.
